Joint Depths and Fillers: <br /> <br />1. Govern depth of joints to receive sealant or caulking by width of joint and achieve by <br />proper placement of joint filler-gaskets. <br /> <br />a. Joints 1/2 Inch and Less in Width: 1/4 inch deep. <br />b. Joints Between 1/2 Inch and 1 Inch in Width: Depth equal to 1/2 the <br />width. <br />c. Joints 1 Inch and Over in Width: 1/2 inch deep. <br /> <br />2. Joint fillers shall be polyethylene or butyl foam cord. <br /> <br />3. Avoid lengthwise stretching of filler materials. <br /> <br />4. Install bond breaker tape at back of joints over joint fillers other than polyethylene <br />type. <br /> <br />B. Epoxy Joint Filler: <br /> <br />1. Transfer entire contents of activator container thoroughly with entire contents of base <br />container in separate container of appropriate size. <br /> <br />2. Mix only as much material as can be applied within manufacturer’s recommended <br />application time period. <br /> <br />3. Mix with slow-speed drill (80-100 rpm) and slotted paddle. Ensure mixing paddle <br />reaches bottom and scrapes side of container several times. Scrape paddle several <br />times to ensure thorough mixing. Keep paddle blade below surface to avoid <br />whipping air into material. <br /> <br />a. Mix Epolith-P for 5 to 7 minutes. <br />b. Mix Epolith-G for 8 to 10 minutes. <br /> <br />4. Pour Epolith-GP from spouted can or professional bulk-loading caulking gun. <br />5. Apply Epolith-G by professional bulk-loading gun. <br />6. Maintain minimum joint application of 2/3 joint depth or 1 inch, whichever is greater. <br />7. Fill joints from bottom up to exterior face by holding properly sized nozzle against <br />joint bottom. <br />8. Tool joint to ensure maximum adhesion to joint sides, correct bead configuration, <br />and a neat joint. Dry tool or dampen tool with Reducer 990. Do not use water or <br />soapy water. <br />9. Apply materials only within manufacturer’s specified application life period. Discard <br />joint filler after application life is expired or if prescribed application period has <br />elapsed. <br /> <br />C. Masking: Tape where required to protect adjacent surfaces. Adhere in continuous strips in <br />alignment with joint edge and remove immediately after joints have been sealed and <br />tooled. <br /> <br />D. Sealant and Caulking Finish: <br />
